Abstract

PARA LA DEMODULACION DE SEÑALES (AS) PORTADORAS MODULADAS SUMINISTRADAS A UN APARATO DE TELECOMUNICACION INALAMBRICO, SE UTILIZA UN COMPARADOR (1212) DE DATOS PARA TRANSMISION DE INFORMACION INALAMBRICO, EN PARTICULAR TRANSMISION DE INFORMACION DECT ESPECIFICA. UNA SEÑAL (RS) DE REFERENCIA GENERADA MEDIANTE LA INTEGRACION DE LA SEÑAL (AS) PORTADORA SE SUMINISTRA A UNA ENTRADA (E2) DEL COMPARADOR (1212) DE DATOS PARA LA DEMODULACION DE LA SEÑAL (AS) PORTADORA. A PARTIR DE UNA CONCORDANCIA CON EL PROTOCOLO DE LA TRANSMISION DECT, DOS VALORES BINARIOS IDENTICOS DE UNA PALABRA (S-BW) DE SINCRONIZACION DEBEN SER RECONOCIDOS JUNTO A LA DEMODULACION, SIENDO MODIFICADO UN UMBRAL (ES) DE DECISION DE LA SEÑAL (RS) DE REFERENCIA MEDIANTE UN VALOR (DES) ERROR. UNA DISPOSICION (16,9,142) DE COMPENSACION ADICIONAL QUE COMPENSA EL MENCIONADO VALOR (DES) DE ERROR SE SUMINISTRA POR TANTO EN LA APLICACION DE TELECOMUNICACION INALAMBRICA.FOR THE DEMODULATION OF MODULATED CARRIER SIGNALS (AS) SUPPLIED TO A WIRELESS TELECOMMUNICATION DEVICE, A DATA COMPARATOR (1212) IS USED FOR THE TRANSMISSION OF WIRELESS INFORMATION, IN PARTICULAR TRANSMISSION OF SPECIFIC DECT INFORMATION. A REFERENCE SIGNAL (RS) GENERATED BY INTEGRATION OF THE CARRIER SIGNAL (AS) IS SUPPLIED TO AN INPUT (E2) OF THE DATA COMPARATOR (1212) FOR THE DEMODULATION OF THE CARRIER SIGNAL (AS). FROM A CONCORDANCE WITH THE DECT TRANSMISSION PROTOCOL, TWO IDENTICAL BINARY VALUES OF A SYNCHRONIZATION WORD (S-BW) MUST BE RECOGNIZED NEXT TO THE DEMODULATION, BEING AMENDED A SIGNAL DECISION THRESHOLD (S) OF REFERENCE THROUGH A VALUE (DES) ERROR. AN ADDITIONAL COMPENSATION ARRANGEMENT (16.9,142) WHICH COMPENSATES THE ABOVE VALUE (DES) OF ERROR IS THEREFORE SUPPLIED IN THE WIRELESS TELECOMMUNICATION APPLICATION.
